Abstract

Objective: The identification of genetic, cellular and molecular components underlying durable resistance in cereals to fungal pathogens. Approaches: The genetic and phenotypic characterisation of resistance in wheat to stripe and stem rust is being undertaken to identify partial, adult plant expressed sources of resistance that are effective against global populations of these pathogens. The microphenotypes of proven durable sources of rust resistance in wheat are being characterised to identify those cellular responses that act as indicators of durable resistance, these cellular indicators providing an assay for the durability of new, unproven sources of rust resistance in wheat. At the molecular level genes and genetic pathways involved in host, non-host and systemic acquired resistance are being characterised in wheat and barley. The functional characterisation of the genes responsible for these durable resistance phenotypes in cereals are being examined towards the fungal species of Magnapothe, the causal agent of cereal blast and Puccinia striiformis and P. graminis, the causal agents of stripe and stem rust, respectively. Novel sources of disease resistance are also being examined in wheat, generated through mutagenesis. Wheat mutants have been selected that show altered disease resistance to the above fungal pathogens. The interaction between the mutation in wheat and the pathogen are being examined at both the field and laboratory level. Potential trade-offs between resistance to one pathogen and susceptibility to another are also being examined, as are the affects of these mutations on plant development and response to other environmental stimuli, particularly abiotic factors.
